Built in 1931 just after a fire, which destroyed the original amphitheatre, the Ford Theatres represents architecture of the Golden Age of Los Angeles. But no nostalgia is authorized. The reference to the Gates of Jerusalem affirms cosmopolitism and majesty, with some confidence into the future, but at the same time a certain kind of sham. And it seems pertinent to play with this false pretense. The Ford will be lightened by the air and full of invisible forces. In a meditative perspective, we could say that to breathe is to think on condition, to not forget air resistance, that is to say the force acting opposite to the relative motion of any object moving, what we call in fluid dynamics: drag.
